  2. Describe what happens to the chambers and valves of the heart during each phase of the cardiac cycle.
  3. Trace the flow of electrical stimulation in the heart.
  4. What causes the lub dub sound of heartbeat?
  5. Define the following: cardiac output, pulse, and blood pressure.
  6. compare the structures of arteries, capillaries, and veins and relate these with their functions.
  7. Why does blood slow down in capillary beds?
  8. What is the function of precapillary sphincters?
  9. Compare the osmotic and hydrostatic pressures at both ends of a capillary.
  10. How do veins transport blood back to the heart?
  11. How does a clot form?
  12. What are the major functions of the lymphatic system?

Additional Questions for Respiration (other guide questions are in the group discussion guide)

  1. What are the advantages and disadvantages of air/water as a respiratory medium?
  2. Define tidal volume, vital capacity, and residual volume.
  3. How does a rise in carbon dioxide levels in the bloodstream related to pH changes and oxygen levels?
  4. Describe cooperativity and affinity as they apply to a hemoglobin molecule.
  5. When does a Bohr shift occur?
  6. Describe how carbon dioxide is transported by the bloodstream.
  7. What is the difference between fetal and adult hemoglobin. Why?

Immunity

  1. Draw a flowchart illustrating the events that occur during an inflammatory response.
  2. Choose any two white blood cells and one type of antibody and sketch a character card for each of them (ala Pokemon cards or M:tG cards) describing their special abilities and attack/defense specialties.
  3. Create Venn diagrams comparing a) B-lymphocytes and T-lymphocytes, b) the characteristics of Class I and Class II MHC molecules, c) humoral and cell-mediated immune responses; d) the primary and secondary immune responses; and e) active and passive immunity.
